WASHINGTON—Canada said Friday it will extend restrictions that bar non-essential travel at U.S. land borders until at least July 21. Reuters reported this week the United States is expected to issue a new extension of restrictions at the Canadian and Mexican borders that are set to expire June 21. The restrictions were first imposed in March 2020 in response to the COVID-19 pandemic and have been extended in 30-day increments. The United States held initial working group meetings this week with both Canadian and Mexican officials, sources told Reuters.
